No. 433,102 3 Claims. (Cl. 2-93) The present invention relates to improvements in coat vent constructions and is particularly directed to a coat construction wherein the vent lining therefor is permanently secured only to the inturned edge portions of the coat back seam thus precluding the necessity of securing the vent lining to the external portions of the coat back material.

The manufacture of mens coats from extremely light weight, thin materials is now commonplace and the problem of incorporating suitable lining material in the back vents of these coats without the unsightly appearance of lines of stitches in the coat pieces is a continuing one.

An object of the invention is to provide a practical coat vent construction having the foregoing characteristics that can be readily incorporated into present coat manufacturing processes by those having only ordinary skill in the art.

Another object of this invention is to provide a coat vent construction made of light weight fabrics that will not pull out or tear in ordinary usage, yet presents a finished appearance to the inside face of the coat whilst leaving the external faces of the coat free of all unsightly vent lining attaching seams and stitches.

These and other objects of the invention will become apparent from the following specification taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a fragmental, interior plan view of the coat back pieces shown in separated, juxtaposition with the fold and stitching lines shown thereon in broken lines.

FIG. 2 is a view like FIG. 1 showing the coat in an initial stage of assembly with the back pieces connected together by the back seam.

FIG. 3 is a plan view of the vent lining prepared for attachment to the coat shown in FIGS. 1 and 2.

FIG. 4 is a section on line 4-4 of FIG. 3.

FIG. 5 is a view like FIG. 2 with the prepared vent lining attached thereto in an intermediate stage of manufacture.

FIG. 5a is a view like FIGURE 5 showing the manner in which the cap is formed on the vent lining.

FIG. 6 is -a view like FIG. 5 showing the completed coat with the vent lining of this invention secured thereto.

With reference to FIG. 1 of the drawings there is shown the inside faces of two back pieces 10 and 11 of lightweight coat material in pre-cut, separated positions; the pair of spaced dot and dash lines 12 and 13 along adjacent edges of the pieces 10 and 11, respectively, representing crease lines along which the material is folded upon itself to produce the book seams 14 and 15, respectively, on each side of the vertical back seam 16. The back seam is shown in flattened and finished condition in FIG. 2 of the drawings wherein it will be noted that the fold lines 13 for the book and central back seams of the back piece 11 extend to the bottom edge of the said piece while the fold lines 12 for the book seam and back seam for the back piece 10 terminate at a lateral cut 17 which produces a fiap 18 projecting laterally from the bottom side portion of said back piece 10. Also in FIG. 2 it is to be observed tht the back seam 16 that joins the pieces 10 and 11 terminates at the lateral cut 17 to form a vent or slit at the bottom of the coat back and that the lateral flap 18 is separated from and superimposed on the lower portion of the back piece 11 in the initial step of assembling the vent pieces.

3,354,469 Patented Nov. 28, 1967 A vent lining 19 cut from a single piece of fabric is illustrated in FIGS. 3 and 4 and may comprise two identical rectangular parts 20 and 21 folded on each other along a central crease line 22. This two ply vent lining is laterally reduced at its upper end by a cut out portion or notch 23 which forms a short lateral edge 24 thereon and is connected together along its top edge by a line of stitches 25 (FIG. 4). The vent lining 19 is then folded on itself along the crease line 26 (FIG. 3) and the flap 18 on the coat part 10 folded upon itself along the crease line 27 (FIG. 2) by first turning the two back pieces 10 and 11 upon their finished faces around the back seam 16 so that the flap 18 projects freely from the back seam 16 and then the vent lining 19 is laid fiat upon the flap 18 with their respective fold lines 27 and 26 in alignment. A line of stitches 28 is then run on the fold.

lines whereafter the back pieces are again returned to their original opened positions and thereafter the vent lining will be superimposed on the joined coat'back in the position indicated in FIG. 5 of the drawing. The vent lining 19 will then be connected to the coat back by the line of stitches 28 (FIG. 5) which permanently secures together the folded edges of the vent lining and the flap 18 of the coat back part 10 all below the slit 17. The vent lining 19 as shown in FIG. 5 is then folded over on itself along the line of stitches 28 to the position shown in FIG. 5a of the drawings and a permanent line of stitches 28 is run in the folds to finally secure together the edge portions of the vent 19 and the flap 18. A triangular cap 29 is then manually formed in the upper part of the vent in the conventional manner and as illustrated in FIG. 5a of the drawings, the upper portion 32 of the vent lining 19 is folded in half along a fold line 33 by bringing the two ends 34 and 35 outwardly and securing said ends together as by tacking (not shown). Next the folded and tacked portion 32, now resembling the prow of a boat, is pushed outwardly from the underside at the position where broken lines 36 and 37 intersect and the portion 32 will fall into the cap configuration 29 shown in FIG. 6 of the drawing, the portion being folded on itself on the lines 36 and 37. The apex of the cap is then tacked to the book seams 14 and 15 of the coat by stitches 30. The final operation comprises forming and sewing the bottom hem 31 of the coat with the lower end portion of the vent lining incorporated into and sewed in said hem.

Thus the vent lining will be secured to the interior face of the inner flap 18 on the coat back part 10 of the finished coat, said inner flap being normally concealed by the outer book seam 13 on the coat back part 11, the upper apex portion of the vent lining being interiorally tacked to the book seams 14 and 15 of the vertical coat seam 16 while the lower end of the lining is secured in the lower coat hem 30. This construction precludes all stitching and tacking into the lower coat facing and provides a strong and finished vent for coats made of lightweight materials.

By usual tailor shop procedures the cutting room may be instructed to form a vent lining blank that is 6 inches in width and of appropriate length depending on the size of the coat, notches 23 being formed therein to a depth of /2 inch and about 2 inches in height. The line of stitches 25 connecting the top of the folded line is /2 inch below the upper edge thereof. The top edge of the flap 18 formed by the slit 17 will measure 1 inch in width before the book seam 12 is formed and 1% inch after such book seam formation whereby super-position of the folded vent lining upon the flap will permit the parts to fall into position for running of the permanent seam 27. Manual formation of the cap 29, following out of the foregoing measurements, will bring its apex into alignment with the seam 16 for tacking thereto.

What is claimed is:

1. A coat vent construction comprising two coat pieces, each provided with a bottom hem and a side edge portion, a lateral cut formed in the adjacent side edge portion of one back piece in spaced relation to said bottom hem, -a vertical seam joining together adjacent side edge'portion's of'the two pieces down to the lateral cut and providing a book seam on the one piece terminating at the lateral'cutand a book seam on the other pieceextending into the bottom hem of said other piece, a flap'formed on the one said piece below the lateral cut and underlying the book seam on the other said piece, said flap having an oblique fold line extending downwardly and outwardly across the flap from a point near the inside end'of the lateral cut'to a point adjacent its lower outer edge, a rectangularly-shaped vent lining securing the top end portion of the vent lining to the interior faces of the book seams, and means securing the bottom of the vent lining to the bottom hem of the one said piece.

2. A coat vent construction as set forth in claim 1 wherein the vent lining has a two ply construction.

3. A coat vent construction as set forth in claim 2 wherein the means securing the top end portion of the vent lining to the interior faces of the book seams of the pieces is a triangular cap formed on the top end portion of the vent lining, and a tacking stitch connecting the apex of the cap to the book seams of the coat pieces.
